Geomembrane sheet is a name that is more common these days for those who want to insulate swimming pools or water storage tanks. Geomembrane is a product that has recently been able to become a suitable, safe, and affordable alternative to Isogam, and other insulations that were used in the past. But you should know that today geomembrane sheet with its unique quality and efficiency has been able to play the role of a suitable and efficient product among consumers and applicants.
Now, in this section of Farnam Baspar’s blog, we would like to introduce you to the geomembrane sheet and its types of applications:
What is geomembrane sheet?
Geomembrane is a sheet made of polymer, which today has been able to replace the old methods of isolation such as (cement, concrete, isogam, etc.). You should know that geomembrane sheets are placed directly on the soil bed and with their special composition, they prevent water leakage or its passage into the bed. It is interesting to know that these sheets are connected to each other by a thermal welding machine, and you can place any number of these sheets next to each other to cover the entire surface of the pool or water storage tanks.
In general, geomembrane sheets are a type of resistant insulation made of soft PVC or polyethylene, which with their special flexibility are very effective for insulating agricultural pools, water storage pools, and other insulations. It is better to know that the use and application of geomembranes is very convenient and worry-free and there is no need for substructure, concreting, etc. In simpler terms, just fill the desired bed with soft soil and then place the geomembrane sheets on it and connect the geomembrane sheets to each other with a special welding machine. These insulators have high impermeability and almost nothing can pass through them. This product is mostly used in the insulation of subway tunnels, swimming pools, water and chemical tanks, roof gardens, elevator pits, transmission tunnels, etc.
Components of geomembranes
Polyethylene is the most used material in geomembrane sheets. This polymer material, which consists of a large number of ethylenes, is chained together to form a large polymer molecule. It is better to know that the primary material of polyethylenes is obtained from crude oil and this material is used in plastic industries, making polymer pipes and geomembrane insulation sheets. Polyethylene has an ideal resistance to acidic and alkaline substances. This property is used in the production of these sheets and by adding stabilizers to the geomembrane formulation, they increase its durability against ultraviolet rays of the sun and environmental oxidants.
The price of geomembranes
The price of geomembrane sheets does not have a fixed rate due to the fluctuations of the market and the price of raw materials, but if you intend to order geomembrane sheet, you can contact Farnam Baspar experts at the sales department to find out the final price. Of course, it should be noted that the price of each sheet depends on its thickness, depending on the type and variety of materials used in its construction.
Geomembrane sheet and its types of application
If we want to talk about the use of geomembrane sheets, we must say that this product is used and exploited in various sectors of agriculture, petrochemical industries, agricultural ponds, chicken farms, water storage sources, waste disposal landfills, etc. due to its high efficiency. Placed. These sheets are produced and supplied in both single and double layers and in fixed colors of white and black.
It should be mentioned that geomembrane sheets are made in sizes and thicknesses of 0.75, 1, 1.5, 2, 2.5, and 3 mm. Also, geomembrane sheets with a thickness of 1.5 mm are the most widely used, and sheets with a thickness of 2 mm and above have a more special application and are usually used in pools with a depth of more than 15 meters.
One of the main characteristics of a geomembrane sheet is its strength and high resistance to different weather conditions, perforation, bursting, heat, etc., which is why it can be a very suitable and good alternative to isogam. Today, these sheets are used to insulate buildings, build roof gardens, insulate gardens and all kinds of buildings.
In general, the applications of these sheets are categorized into three general groups:
Being waterproof
Separation and isolation
protection
According to these three categories, geomembrane sheets can be used for a wide range of applications. Some of the applications of geomembrane sheets are:
Agricultural tanks, canals, tankers, prefabricated tanks, sewage treatment plants, discharge boats, fish farms, chicken and animal farms, golf courses, and…
Municipal waste landfills, leachate treatment boats, mining waste boats, and water treatment plants.
Leak protection systems in petrochemical industries, airports, and port areas, storage of industrial waste, etc.
In civil works such as roads, walls, tunnels, railways, etc.
Covering swimming pools, wetlands, artificial lakes, etc.
Covering oil reserves, chemical reserves, and…
Insulation of pools, including fish farming
Agricultural industry (to cover earthen pools to store water for irrigation)
Isolation of tunnels and mines
Covering water reservoirs
As an insulating sheet on the bottom of artificial lakes
Garbage disposal systems and urban waste
Types of geomembrane sheets
In general, geomembrane sheets are divided according to the amount of resin used. Also, one of the most important factors that affect the price of these sheets is their type. Join us as we continue to examine the types of geomembrane sheets…
HDPE geomembranes
High-density polyethylene forms one of the most widely used geomembranes, namely HDPEE, which is one of the best choices for lining in Projects known.
HDPE geomembranes are often used in projects that must not leak, such as landfills, tank linings, as well as pond and water channel linings. The low initial cost of materials and their high resistance to chemicals are the most important features of this type. HDPE has a higher thickness than other types. Also, it is very strong compared to its weight and shows great resistance against higher temperatures.
One of the best features of these geomembranes is their resistance to chemicals and UV rays, which makes them suitable for a wide range of applications that require the installation of high-quality materials. In addition, HDPE is safe for food and can be used to store drinking water.
LLDPE geomembranes
In general, linear low-density polyethylene (LLDPE) geomembranes have relatively higher flexibility than HDPE and are more suitable for installers who require impermeable types. It is better to know that this product is made with virgin polyethylene resins and makes the insulation resistant to low temperatures and exposure to ultraviolet rays.
Years of resistance and high durability and application in industries such as water storage tanks, and animal, human and environmental waste landfills are among the most important characteristics of LLDPE geomembrane sheets, which distinguish it from other geomembrane sheets.
PVC geomembrane sheet
Polyvinyl chloride (PVC) geomembrane is a thermoplastic waterproofing material made from vinyl, softeners, and stabilizers. Polyvinyl chloride resin used for PVC geomembranes is made by breaking down ethylene dichloride into vinyl chloride monomer. Then, this material is polymerized to make PVC resin.
This material is resistant to tearing, puncture, and wear. This means that PVC is suitable for preventing contaminants from entering water sources and preserving drinking water. PVC geomembranes are very flexible and suitable for burying waste and canals, covering tanks, soil treatment, and sewage lagoon liners.
EPDM geomembranes
Ethylene Propylene Diene Monomer (EPDM) geomembrane is a flexible and durable material that can show high resistance against perforation and severe weather conditions. EPDM has a texture similar to rubber and is very resistant to UV rays.
EPDM geomembranes are commonly used as surface barriers for dams and other irrigation sites. These insulators are easy to install. This is why backyard designers use this type of geomembrane. In addition, EPDM is suitable for agricultural applications such as irrigation ponds as well as liners and covers.
RPP geomembranes
Reinforced polypropylene (RPP) geomembranes are reinforced polyester covers for long-term water and industrial waste applications. This type is made from a UV-stabilized polypropylene copolymer that gives the material flexibility, stability, and chemical resistance.
RPP geomembranes are an excellent alternative to insulations that get wrinkled due to uneven and inconsistent weather conditions. To ensure that these insulators remain strong and durable, they are supported using a nylon skim. This type of geomembrane is usually used in urban, aquatic, and horticultural uses, linings of evaporation ponds, and mine waste.
TRP is one of the best geomembrane sheet
Reinforced polyethylene (TRP) geomembranes are almost similar to RPP, but in their construction, they use polyethylene fabric instead of polyester. This insulation is an ideal option for covering your temporary holding ponds.
Also, TRP geomembranes are a sustainable solution for soil remediation. Its physical properties include chemical resistance, low-temperature range, and stability against ultraviolet rays. This type of geomembrane is used for channels, industrial tarpaulins, landfills, and agricultural and urban uses.
